I've successfully triggered a deployment using a webhook + automations. Is there any way to access the raw event payload from the triggering event in the context of a flow?

Congrats! Also yes, definitely. When setting up the action for your automation, you should see a field to set a parameter for the new deployment run. In the parameter field you can pass in something like:

{{event.payload.some_value}}

to use a value from your event payload. You may also need to make sure that "jinja" is selected in the hamburger menu on the right-hand side of the parameter field in the form.

Thank you @Bianca Hoch!

yup ofc, reach out if you hit a snag!
